Linus,

Update bootconf scripts for tracing_on option

The tracing_on option is supported by bootconfig entries, but the scripts to
convert from ftrace to a bootconfig and back were not updated.


Please pull the latest trace-v5.11-rc3 tree, which can be found at:

    tools/bootconfig: Add tracing_on support to helper scripts
    
    Add ftrace.instance.INSTANCE.tracing_on support to ftrace2bconf.sh
    and bconf2ftrace.sh.
    
    commit 8490db06f914 ("tracing/boot: Add per-instance tracing_on
    option support") added the per-instance tracing_on option,
    but forgot to update the helper scripts.
